Pajero Exceed 2.8D gear Shifting problem

[maaztahir17]

Pajero exceed 92 model, and 4 months before i swapped it engine to 4D40 Auto transmission.
There is some problem in transmission. Whenever i drove it on motorway or GT road, at speed of 80Kmph or 90 or 100, it downshifts to 3 gear automatically, Then if stay on 80KMPH it continuously shifts between 4th, 5th and 3rd gear. OD is not the problem, whenever i turn of OD it stay in 3rd gear when i rave it to 100KMPH, as soon as i turn it on, it starts shifting.
1: I have tried 10 to 15 computers
2: Main Ground wire is prefect
3: this computer cannot be attached with devices to scan for error.

Dear have you have the transmission fluid replaced / drained and re-filled with the OEM Spec Fluid

Check the tps(throttle position sensor)
I had a similar problem which resolved after changing tps

I faced similar problem in my pajero with 3.5l dohc engine. It got resolved after replacing 3 solenoids. I was not aware that it can be solved without replacing them. Spent 20k on the job.

Please tell some good mechanic for my pajero 96 3.5 dohc engine. I have searched and tried many but most of them seems to be doing experiments with my jeep. I'm from ISLAMABAD. Thanks .

what is the engine temperature when the transmission starts to act silly?

[maaztahir17]

Thankyou very much giving me your time and guiding me,
The issue is resolved, i went to a machanic for some brake issue, he told me to replace calipers and i did that which exentually resolved my shifting issue aswell, i guess brakes were applying pressure or idk what but coz some pressure was tgere which was restricting the gesr shift.
